FREEZING APPARATUS

摘要

A contact freezer consists of a series of freezing plates (12) in which freezing medium is circulated in the interior. The plates are movably connected at a predetermined interval in an elevational direction. First elevation cylinders (14) raise the top freezing plate (12a) until the respective plates are suspended and lower them so that the adjacent plates make contact with freezing pans (17). Second elevation cylinders (16) raise or lower at least one specific freezing plate in the state that respective plates are suspended to dispose the bottom freezing plate (12m). An engaging or disengaging mechanism (18,20) engages the specific plate with the second elevation cylinder.
